Abstract
A nuclear power plant containment cooling system and a spray flow control method therefor. The system comprises a cooling system liquid tank () for storing cooling liquid, wherein the cooling system liquid tank () is provided at the top of a containment () and the cooling liquid is used for cooling the containment () through the gravity of the cooling liquid itself in the situation of an accident, and the cooling liquid is partially evaporated. The nuclear power plant containment cooling system further comprises an adjustment mechanism; wherein the adjustment mechanism is provided at a liquid outlet of the cooling system liquid tank (), and the adjustment mechanism is used for controlling the flow at the liquid outlet according to buoyancy generated by a liquid level of the collected cooling liquid which is not evaporated.
